Jacket waterproof rating mm.

The higher the number of millimetres the more waterproof the jacket is. All of our waterproof garments come with a waterproof protection rating measured in millimetres mm. For example a rain jacket with a waterproof rating of 20 000 means that if you had an endlessly long 1 inch square tube you could pour 20 000 millimeters of water on top of the fabric before it. Except for the waterproofness this jacket is also very durable comfortable and doesn t sacrifice a lot of mobility when wearing it.

Now though the brand is rapidly rolling the tech into everything from hiking footwear to tents. When choosing a waterproof jacket or trousers it is important to understand the limitations of the garment you choose. 10 000 mm is enough to keep you dry on most regular hiking trips. For your reference i suggest waterproof hiking jackets with ratings starting from 10 000 mm.

While the range between 5 000 mm and 10 000 mm is excellent for spending long days outdoors through cold and wet weather conditions. If you ride primarily in cold and clear conditions and take regular lodge breaks this level of protection could be fine but anything less and you stand a good chance of getting wet and cold in a storm. For example a jacket with a hydrostatic head rating of 2 000mm is not going to withstand a heavy prolonged downpour where a jacket with a rating of 20 000mm is designed for these conditions. Jackets with a rating of 1 500mm to 2 000mm are suitable for everyday use whether it be around town or walking the dog.

This is the minimum rating for a jacket to be called rainproof however it won t stand up to much more than a light shower. 28 000 mm is real luxury. 5 000 mm is also the minimum waterproof rating for ski and snowboard jackets. The best waterproof jacket is the paramo alta iii.

These jackets may also be suitable for walkers or hikers who aren t likely to get caught out in heavy sustained rain. Waterproof ratings beyond 10 000 mm are best suitable for avid skiers snowboarders and mountaineers. Anything less than 5 000 can get you wet and cold in a storm. We recommend a minimum waterproof rating of 5 000 mm or 5k for ski and snowboard jackets and snow pants.

When the north face released its futurelight waterproof fabric technology in late 2019 it only showed up in outerwear made for skiing snowboarding and other mountain adventures.
